venlor A llomcy Patented Sept. 29, 1931 UNITED STATES CHARLES A. RIVAS,or s'r. Louis, Missounr SHOE AND PROCESS MAKING SAME Application filedFebruary 20,1930. seriai No. 420,903.

This invention relates to new and useful improvements in shoes andprocesses of making the same and more particularly to the soleconstruction of the shoe and the method 6 of attaching the same to theupper.

An important feature of the invention resides in the process of securingthe insole and welt to the upper in such a manner that all of thesecuring nails'have their points disposed outwardly and wherein saidnails will be entirely concealed from view on both the inside andoutside of the shoe.

7 Another important object of the invention is to provide means forattaching the insole, welt and upper together by means of securing nailsin such a manner that the foot of a wearer cannot come into contact withsaid nails. 7

Another important feature of the invention resides in the method ofsecuring the upper, welt and insole together whereby great speed andaccuracy may be obtained in'the process of manufacture. v

Other objects of the invention are to provide, in a manner ashereinafter set forth, means for attaching the upper, welt and in soleof a shoe together which will be extremely simple, strong, durable andwhich may be manufactured at low cost.

All of the foregoing and still further objects and advantages of theinvention will become apparent from a study of the followingspecification, taken in connection with the accompanying drawings,wherein like characters of reference designate corresponding partsthroughout the several views, and wherein Figure 1 is a longitudinalsectional view showing the insole constituting a part of this inventiontemporarily mounted in position on a last, the securing nails beingmounted in position on said insole.

Figure 2 is a view in side elevation, partlybroken away and showing theinsole with the upper attached thereto, said upper being stretched overthe last.

Figure 3 is a View in bottom plan showing the welt stretched in positionover the nails, said nails being bent over in a manner to 5 clinch thewelt thereon.

" Figure 4' is-a view in bottom: plan of the k completed shoe. I p

Figure?) is a View in'cross section taken through'the toeportion of acompleted shoe constructed in accordance withthis inven- EIOI'L-"HT'Figuret is vaview in top plan, partly broken away, of the insole forminga part of this invention. I

- Referringto'the drawings in detail, it will be seen that the referencenumeral 1 designates the insole of the shoe. The entire periphery of theinsole 1 is slit to a suitable depth as indicatedat 2 to provideupperand lower marginal portions 3and 4, respectively. A series of spacedsecuring nails 5 are projected through the lower marginal portion 4 withthe heads thereof disposed in the slit 2 and the insole 1 with the nailsthus mounted therein is temporarily tacked in the usual manner on thelast 6.

The shoe upper 7 is then assembled on the last and the inturned portionsthereof are pushed over the projecting points of the nails 5 in themanner clearly indicated in Figure 2 of the drawings. The welt 8 is thenpushed on to the nails 5 and said nails are bent over in a manner toclinch saidwelt in position. It will thus be seen that the insole 1, thewelt 8 and the upper 7 are securely fastened to gether. Suitable means(not shown) may be provided whereby the operation of forcing the welt 8over the nails 5 and clinching said nails on the welt may beaccomplished in the same operation.

The outer sole 9 is then stitched in thensual manner as at 10 to thewelt 8, a filler 11 of suitable material being first inserted betweensaid outer sole and the insole 1.

When the last 6 is withdrawn it will be seen that the upper marginalportion or flap 3 completely conceals the heads of the nails 5 and inaddition serves as a shield for preventing the foot of the wearer fromcoming into contact with said nails. 7

It will be further apparent that, with the proper equipment, a processhas been provided for assembling the upper, welt and insole of a shoewith great speed and facility and at the same time produce a shoe ofhigh quality and durability and which will be further distinguished byattractiveness in appearance.

It is believed that the many advantages of 5 a shoe constructed inaccordance with this invent-ion and by this process will be apparent,and although the preferred embodiment thereof is as illustrated anddescribed. it is to be understood that various changes may be had whichwill fall within the scope of the invention as claimed.

lVhat is claimed is The method of making shoes consisting in forming aslit in the marginal edge of an in sole in a manner to provide upper andlower flaps extending around'the insole, inserting nails through thelower flap from the inner side thereof, securing the insole temporarilyon a last, turning inwardly certain of the marginal portions of a shoeupper beneath the lower flap and impaling the marginal upper portions onthe nails, placing a filler on the insole Within the impaled marginalupper portions, impaling a welt on the nails over 5 the impaled marginalupper portions and certain of the marginal portions of the filler,clinching the nails on the Welt, and securing an outer sole of the welt.

In testimony whereof I aflix my signature.

CHARLES A. RIVAS.
